Figur@ lla'tp Plan View of "a portable* sired thickness. Mounted upon the top of base 1 is a rectangular platform 2 corresponding in contour to and having its sidey and end edges flush with the outer edges of 5 the base 1. The platform 2, at each corner thereof, is secured to the base 1,.by the rivets 3. The rivetshave rounded heads 4, similar to the heads of carriage bolts. The heads 4 depend from the base 1 and function substantially as rollers so that the machine may be shifted aboutV on the floor of a garage or repair shop; Y

l Secured upon the platform 2, in proximity to one end thereof and also to one side of the longitudinal median of said platform 2 is an electric motor 51 having a controlling cord 7 leading therefrom. The. cord 7 includes a circuit closing and opening member 6 of the push-button type.` The cord 7 is of aVY length to extend under the automobile being prefor a Worm 9 which is carried by shaft Hl0, the

latter beingcoupled as at 11 With thevmotor i 3ishaft 12. -Thesh'aft 10 projects from thejhousing 8 and is suitablyjournaled therein.

The housing 8 `includes abase 13, through,

j which extend holdfast devices 14 for xedly securing it to the platform 2. The motor 5 is T carried by ai standard 15, Xedly secured with Y the platform 2 by the holdfast devices 16.v

`Arranged between the transverse median and yother end of the platform 2 and also at each side `of thelongitudinal median of theV 'olatter is af rotatable Wheel driving spool or drum substantially in the form of and termen a nigger'head.. -The heads are indicated generallyv at 17, 18.y The heads are arranged in parallel spaced relation. Eachlhead includes -a1body 19ofv circular crosssection and Which y gradually increases in diameter from its transverse centerV toward eachend wherebyL Y ly,-are carried respectively by the bearing 24 and one end of head 17 and VWhichcoact to lockv head '17 andprevent the operation of the 'body' 19 inlongitudinalsection vwill be u x concavlofconvex. The periphery ofthe body 1 9 "b1-is constructed'in a Vmanner jto provide` a roughened' surface upon which the Weight of the automobile is applied, under such conditions creating a tractionv surface lfor the laty ter. As illustrated,1the periphery of the bodyV "#13519 has proj ecting. there/from a series offclose-Y ly arranged' circular protuberances V2.0. Itis to :be understood however that the periphery of the body 19 can be formed in a manner other than shot-vn to create a traction surface iand'that the/circular *protuberances 20 are illustrated as 1 one tended@V n v L `The machine further includes a drive shaft forja head`19 and suchfshaft isformed of means Yfor the purpose in# two* endWise aligningsections 21, 22. Fixedto the sectionV 21, intermediate the ends thereof, is the head 17. Supported bearings 23, 24 are provided for the section 21. The bearing 23 is arranged adjacent the inner end of the shaft section 21.Y

Fixed to the inner end of the shaft section 21 is a sprocket wheel 24, having one side formed `With Aa circular 'offset 25 provided With an annular groove 26 having its bottom tapered. The bottom of the groove 26 is indicated at 27. Operating in the groove 26 1s a pairof spring controlled pins 28 carried by a disk 29 which is fixed to shaft section 22. The disk 29 is provided With a pair of socket forming members 30, carrying the controlling springs 31 for therpins 28.l -The sprocket pinion 24 is fixed to the shaft section 21,as at 32. YTheshaft section 22 extends through a supported-bearing 33 and also through the vhousing 8. The shaft section 22 carries a pair o offstop collars 34 which abut against opposite sides of thehousing 8 and also carries a Worm gear 35 which ispositioned in housing 8 and is engaged and operated by a Worm 9.

Aligning with the supportedbearings 23, 24 respectively, as Well as being spaced there-V from,are supported bearings36, 37 in Which isrotatably mounted a shaft 38 for the head 18. The head 17 is fixed to the'shaft member "21 andthe head 18 to the shaft 38.v The head i V181s;simultaneously rotated `With respect to the head 17 'andis driven from thesprocket Wheel`24.Y Fixedto the inner end of shaft 38 Y is a sprocket pinion 39 which 4is driven from sprocket pinion 24Vby an endless link chain 40. y.

The elements 26, 27, 28, 29, 30 and 31 constitute` afriction clutch to provide for the operation vof the head 17 from the motore,` when shaft 1() is operated. The arrangement also provides for the non-driving of the shaft section 22V when the heads 17 .and:18 are driven from the Wheel of the automobile.`

VTo prevent the rotation of heads 17 and 18 when the automobile Wheel is being mounted therein .from vone direction, a pawl and a ratchet device, indicated at 41, 42 respectiveheads Y18,Y 17 and a ratchet device 43, 44connected respectivelyto the bearing 37 and head 18 and Whichcoact to lock head 18 and pretomobile Wheel on the heads from but oneside of the machine,butwith the employment of the twostopdevices the automobile VWheel can Vvent the rotation of head 17. It is toibe unf be mountedfand removed from either side of p f the -machine Without rotating the heads 17, 18.

1t is to beunderstood that thev pawl and ratch- V.et devices shown are illustratedfmerely by removed from the nigger heads.

Way of ezample, as any suitable means can. be employed in connection with theheads 17, 18 to Aprevent'the rotation thereof whenthe automobile Wheel is being mounted upon or The height ofthe-machine is such as to position the nigger heads suiliciently clo'sefto f `Vthe floor that anautomobile Wheel'lnay be easily backed or run upon the machine while g' thelatter is'sitting on the floor.
